thatgirlmarmar Lookmovie posts content across all ratings platforms. Standard viewer advisories are displayed if included in the original content. Just as with any streaming service, it's ultimately up to the end user's (in this case the parent's) discretion to make those kinds of judgements with regard to who is allowed or not allowed to view the content provided.
In the "Categories" drop down menu, you also have the ability to select "Family," which will display only family suitable content.
